OK I live in a apt. and have a 2 piece CB base antenna "Patriot 12' fiberglass" up as high as I could get it for my base station. Now I just purchased another scanner and would like an outside antenna though the land lord has not complained I feel a little funny putting up another antenna. My question is would I gain anything over the little attached scanner antenna if I used an antenna switch and tried to use my CB antenna to cover mainly the 400mhz UHF area" no 800 or trunked system here yet" for my scanner?
